More about the KVM-SF
The KVM-SF is a fully integrated controller capable of directly driving single phase fans up to 8 amps, it also provides a built in current sensing interlock to monitor those fan outputs. The system has an input for a CO2 sensor which can vary the fan speeds to ensure the working environment is kept safe. If the Co2 level continues to rise then the system can isolate the gas to ensure staff safety.
If 3 phase fans are being used then the system also has signal outputs to drive invertors. Air pressure switches or remote current sensors can be installed and wired into the spare inputs in the panel.
The KVM-SF is a comprehensive controller that is also capable of satisfying installations where solid fuel appliances are installed.
